Reactions of Aromatic Molecules - Master Organic Chemistry
The Mechanism of Nucleophilic Aromatic Substitution Taking all of these observations into account we can now propose a mechanism for this reaction. The first step is attack of the nucleophile on the electron-poor ring to generate a negatively charged intermediate (e.g. the "Meisenheimer" intermediate, above)

Nucleophilic aromatic substitution - Wikipedia
A nucleophilic aromatic substitution is a substitution reaction in organic chemistry in which the nucleophile displaces a good leaving group, such as a halide, on an aromatic ring.Aromatic rings are usually nucleophilic, but some aromatic compounds do undergo nucleophilic substitution. Just as normally nucleophilic alkenes can be made to undergo conjugate substitution if they carry electron ...

Nucleophilic Aromatic Substitution - The Benzyne Mechanism
An addition-elimination mechanism here doesn't seem right, considering that nucleophilic aromatic substitution reactions with far stronger electron withdrawing groups (e.g. NO 2, rather than Cl) require higher temperatures and longer reaction times.. Another observation was that no reaction occurred under these conditions when the ortho- positions were attached to alkyl groups.
